Terraform provider not updating SMS MFA enrollment template

We are using terraform to deploy changes to Auth0. We have this code snippet:

resource "auth0_guardian" "mfa_guardian" {
 policy = "never"
 email = false
 otp = false
 recovery_code = false
 phone {
  provider = "phone-message-hook"
  message_types = ["sms"]
  options {
   enrollment_message = "Custom message here. When prompted, enter the following 
   security code - {{code}}."
   verification_message = "Custom message here. When prompted, enter the following 
   security code - {{code}}.
  }
 }
}

When deployed, terraform is able to acknowledge this code. However, the Auth0 enrollment and verification template for Phone Message MFA does not get updated.


Can you let me know why it's not working?
